Ç WARNING These instructions do not replace the need for utility operation standards. Any conflict between the information in this document and utility practices should be reviewed by appropriate utility personnel and a decision made as to the correct procedures to follow. Serious risk of personal injury or death may result from contact with electric distribution equipment when electrical isolation and grounding procedures are not followed. The equipment described in this document must be operated and maintained by qualified persons who are thoroughly trained and understand any hazards that may be involved. This document is written only for such qualified persons and is not a substitute for adequate training and experience in safety procedures for accessing high-voltage equipment. The S&C 5800 Series Automatic Switch Control is connected to switchgear operating at primary voltage levels. High voltage may be present in the wiring to the switch control or the switch control itself during certain failures of the switchgear wiring or grounding system, or due to a failure of the switch itself. For this reason, access to the switch control should be treated with the same safety precautions that would be applied when accessing other high-voltage lines and equipment. Follow all locally-approved safety procedures when working on or around this switch control. Before attempting to access an existing switch installation, check carefully for visible or audible signs of electrical or physical malfunction (do this before touching or operating the switch control or any other part of the installation). These warning signs include such things as smoke, fire, open fuses, crackling noises, loud buzzing, etc. If a malfunction is suspected, treat all components of the installation, including the switch control and associated mounting hardware, as if they were elevated to primary (high) voltage. Whenever you are manually reconfiguring the circuit (for example, during repairs), follow your company s operating procedures to disable automatic operation of the S&C 5800 Series Automatic Switch Control. This prevents any unexpected operation. 4 S&C Instruction Sheet

Operator Failure Override This field displays an Active message when the SCADA operator sends a Failure Override command to the switch control. This command enables the line switch to be opened and closed by the operator even if the battery is low. Remote Switch Set Remote This field displays an Active message when the faceplate REMOTE/LOCAL switch is in the REMOTE position. Auto Switch Set Enabled This field displays an Active message when the faceplate automatic operation ENABLE/ DISABLE switch is in the ENABLE position. A Stop Transfer condition will exist if automatic operation is disabled. Tamper Switch (Door Open) This field displays an Active message when the switch control enclosure door (S&C 5801) or low voltage cabinet door (S&C 5802/5803) is open. Trouble Conditions These are conditions which clearly indicate a problem, but may not prevent line switch operation. Battery Low This field displays an Active message when the predicted battery voltage under load is below the Battery Low setpoint. For more details, see the Operations Instruction Sheet Battery Charger Bad Call S&C. This field displays an Active message when the battery is being charged at an abnormally high voltage. The PS/IO board may need to be replaced. This message also reports when the load resistors are disconnected from the PS/IO board at J11. Open/Close Contacts Bad [Switches 1, 2, and 3, if applicable] This field displays an Active message when the open and close contacts on the line switch are not mutually exclusive, and the switch is not in motion. S&C Instruction Sheet

18 Temperature Sensor Bad This field displays an Active message when the switch control s temperature sensor reads outside of its valid range. Electronics Bad An internal problem has been detected that may affect the operation of the switch. Contact S&C for assistance in diagnosing the problem and determining the correct action to take. Figure 5. Troubleshooting: Event Status screen page 2 (5801 shown). Switch Not Ready Conditions These are conditions which will prevent operation of the line switch.

19 Low Pressure (if appl.) (Vista switches) If applicable, this field displays an Active message when the switch control detects low pressure inside a switch (operator) equipped with low pressure sensing. Switch 1 in Local Mode (PME and PMH switches) Switch 2 in Local Mode (PME and PMH switches) Switch 3 in Local Mode (PME and PMH switches) This field displays an Active message when the external REMOTE/LOCAL switch on this pad-mounted switch, located in the PM Operator compartment, is set to LOCAL. Switchgear in Local Mode (Vista switches) This field displays an Active message when the external REMOTE/LOCAL switch on this switchgear is set to LOCAL. Position 1 Grounded (Vista switches) Position 2 Grounded (Vista switches) This field displays an Active message when this switch has been opened and put in the grounded position. Hot Line Tag The Hot Line Tag feature modifies the automatic and manual operation of the switch and prevents the control from closing the switch when it is applied. Hot Line Tag can only be Set and Cleared with a SCADA command. Latch On sets Hot Line Tag, and Latch Off clears Hot Line Tag. A binary Status Point communicates the Hot Line Tag state, where a value of 1 indicates Active status, and a value of 0 indicates Inactive status. Hot Line Tag may only be set if the following conditions are true: The switch must be Open, Switch contacts must be consistent, No switch operation is pending. If any of these three conditions are not met, the control will return a hardware error 1 response to the SCADA command to set Hot Line Tag, and the tag will remain Cleared. Whe Hot Line Tag is set or active the Scada-Mate Switch is inhibited from Closing by all means: Locally by a front-panel command, Locally via directly-connected IntelliLINK software, Remotely via IntelliLINK Remote Software, Remotely by a SCADA command. The sole exception to the Close inhibit is the local operating mechanism (hotstick operation) on the Scada-Mate Switch. The 5801 embedded control software is locally overridden by the operating mechanism. Such operation will not result in the tag being cleared, and the control will still be inhibited from performing any Close operations. Hot Line Tag status is displayed in the Maintenance category of the LCD display. When Hot Line Tag is set, the tag status will be displayed with the message: Caution: Hot Line Tag Applied. As long as the Hot Line Tag remains active, LCD data scrolling will be disabled and only the Hot Line Tag status message will be displayed. When the Hot Line Tag is inactive, confirmation of this status will be provided by scrolling the LCD data display to the Hot Line Tag status under the Maintenance category, which will display the message: Hot Line Tag Cleared.

It can provide additional information about the packet received. For more details, see PG&E SCADA protocol documentation. Cmd This is the PG&E SCADA command code for this communications malfunction. It can provide additional information about the packet received. For more details, see PG&E SCADA protocol documentation. Various Counters The TROUBLESHOOTING: Various Counters screen (Figure 12) contains counters and statistics associated with DNP communications. To display the TROUBLESHOOTING: Various Counters screen: Click the Troubleshooting button at any IntelliLINK screen, then click the Various Counters button. S&C Instruction Sheet

28 Figure 12. TROUBLESHOOTING: Various Counters screen. The switch control counts and records errors and events associated with the interrupt service routine, the data link layer, and the application layer. The counts are stored in non-volatile memory, but may be cleared if necessary. To clear the counts in both pages of this screen: a. If you want to save the count information on the screen, generate a report. IMPORTANT: Once you clear the counts and statistics, the data cannot be recovered. b. Click on Clear All in the upper right corner of the screen. This causes all counters and statistics to return to 0, except the Min 2way which clears to the maximum value of 255. The fields on these screens are grouped into four categories: Receiver Interrupt Counts, Application Layer Counts, Data Link Layer Counts, and Communication Statistics. Receive Interrupt Counts These are errors associated with the communications interrupt routine. If applicable, the data for each port is shown separately. Bad CRC This field shows the number of failed CRC calculations on incoming packets. Simul. Rcv/Xmt This field shows the number of times the receiver and transmitter were enabled simultaneously. 28 S&C Instruction Sheet

29 Bad Address is field shows the number of packets that were received with a destination address that does not match the RTU address of the local switch control. Bad Preamble This field shows the number of packets that were received without the required 2-byte DNP packet preamble of 0564 hex. Bad Length This field displays the number of packets that were received with an invalid length. Invalid packet lengths are values less than five. Bad Framing This field shows the number of times the UART received an improperly framed byte. Rcv Busy This field shows the number of times a packet was unable to be received due to a busy receive channel. Xmt Busy This field shows the number of times a packet was unable to be transmitted due to a busy transmit channel. Application Layer Counts These are errors associated with the application layer of DNP communications. Bad Function This field shows the number of times an invalid or unsupported function code was received. Bad Object This field shows the number of times an invalid or unsupported object code was received. Bad Pkt Param This field shows the number of times an invalid or unsupported packet parameter was received. Packet parameters include the variation, qualifier, and indexing associated with the object. Comm in Local This field shows the number of times that Remote mode was changed to Local mode during communications. Rcvd Broadcast This field shows the number of times a packet containing the broadcast destination address was received. S&C Instruction Sheet

30 Time Sync Req This field shows the number of requests made for timestamps by toggling the associated IIN bit on. Bad Pkt Seq This field shows the number of mismatched application layer sequence numbers that were received in packets. Bad Fir/Fin This field shows the number of packets received with the Fir and Fin bits set improperly. Xmit Delay This field shows the number of times that the transmit of a packet was delayed due to interrupt or data link layer activity. A large number in this field does not indicate a problem, although a problem may exist if the number is continuously incrementing. Defr Rd Lost This field counts the number of deferred-read requests that were overwritten by subsequent deferred reads. DNP requires that the switch control defer simple read requests if it is waiting to receive confirmation from the master station for an outstanding eventdata response message. Other Err This field shows the number of unidentified errors encountered. Data Link Layer Counts These are errors associated with the data link layer of DNP communications. App Layer Busy This field shows the number of times a confirmed user data packet was received into the data link layer but could not be delivered to the application layer due to existing application layer activity. Confirmed packets that cannot reach the application layer cause an ack confirmation to be sent to the sender of the packet. Unconf Fail This field shows the number of times an unconfirmed user data packet was received into the data link layer but could not be delivered to the application layer due to existing application layer activity. These unconfirmed packets are dropped, without notifying the sender. FCB Mismatch This field shows mismatch occurrences of the Frame Control Bit (FCB) in the data link layer. 30 S&C Instruction Sheet
